There are many kinds of commonly used screw materials, roughly two kinds, one is carbon steel, that is, iron, carbon steel can be divided into low carbon steel, medium carbon steel, high carbon steel. The other is stainless steel, stainless steel has stainless steel SUS201.304.316 and so on.

To a certain extent, the quality of the screw material determines the quality of the screw itself. Therefore, manufacturers of the screw industry must choose a good quality screw material to produce. In the better guarantee the quality of the screw.

The below screw is made by us, customized, made of low carbon steel, Black Zinc.
